Disruption of nucleotide biosynthesis reprograms mitochondrial metabolism to inhibit adipogenesis

Journal of Lipid Research
A key organismal response to overnutrition involves the development of new adipocytes through the process of adipogenesis. Preadipocytes sense changes in the systemic nutrient status and metabolites can directly modulate adipogenesis.

Orotic Aciduria [PDF]

, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

Chemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Purinosomes involved in the regulation of tumor metabolism: current progress and potential application targets

Frontiers in Oncology
The core of tumor cell metabolism is the management of energy metabolism due to the extremely high energy requirements of tumor cells. The purine nucleotide synthesis pathway in cells uses the purinosomes as an essential spatial structural complex.

Diagnosis and epidemiology of red blood cell enzyme disorders

Thalassemia Reports, 2013
The red blood cell possess an active metabolic machinery that provides the cell with energy to pump ions against electrochemical gradients, to maintain its shape, to keep hemoglobin iron in the reduced (ferrous) form, and to maintain enzyme and ...

Single molecule DNA sequencing via transverse electronic transport using a graphene nanopore: A tight-binding approach

, 2016
We report a tight-binding model study of two-terminal graphene nanopore based device, for sequential determination of DNA bases. Using Greens function approach we calculate conductance spectra, I-V response and also the changes in local density of states

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications

Chemistry – A European Journal, EarlyView.
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

Comparative genomic analysis reveals a critical role of de novo nucleotide biosynthesis for Saccharomyces cerevisiae virulence.

PLoS ONE, 2015
In recent years, the number of human infection cases produced by the food related species Saccharomyces cerevisiae has increased. Whereas many strains of this species are considered safe, other 'opportunistic' strains show a high degree of potential ...

Boron Neutron Capture Therapy at a Crossroads: Translational Gap and Emerging Delivery Agents

Chemistry – A European Journal, EarlyView.
This review surveys recent advances in boron delivery agents for BNCT, emphasizing the shift from classical small molecules to multifunctional nanocarriers and theranostic systems. By integrating targeting, imaging, and therapy, next‐generation boron compounds aim to bridge the gap between (bio)chemical innovation and clinical translation.

ProTides for Antiviral Activity Beyond Liver Cells

Chemistry – A European Journal, EarlyView.
A strategy for obtaining prodrugs of antiviral nucleotides with broad tissue activity is presented that relies on cycloalkyl or cycloalkylalkyl esters, improving uptake and esterase cleavage, and producing nanomolar inhibitors in kidney, colon, and lung cells.
